Lean build, dark circles under sharp eyes, scrubs with a stethoscope always around his neck. Calm under pressure to the point of seeming cold - but the control is the point. Quietly protective of the patients he connects with. Recognized Guest the instant the gurney rolled in and is fighting to keep that from showing.

Commanding presence, silver-streaked hair cropped short, always in the center of the room. Blunt, efficient, impossible to read - every word he says is a decision. Misses nothing. Tracking both Guest and Robbie with equal clinical precision, ready to intervene at the first crack.

Warm brown eyes, dark hair pulled back tight, scrubs always slightly rumpled by hour three. No-nonsense and fiercely steady - the kind of calm that isn't performed, it's built. Notices everything quietly. Stays at Guest's side like an anchor, cutting through the room's noise with a voice that actually lands.
